SPECIFICATION forming part of Letters Patent No. 286,458, dated October 9, 1883. v

Application filed March 26,1888. (No modeld To all whom it 12mg, concern.-

Be it known that I, Honecn F. Honors, a citizen of the United States, residing at Chelsea, in the county of Suffolk and State of lvlassachusetts, have invented certain new and useful Improvements in Oil-Cups, of which the following is a specification.

My invention relates to that class of oil-cups in which the oil is caused to enter a steampipe or other steamspace containing steam under pressure.

The invention consists of an apparatus in which the gravity of the oil constitutes the force by which it is made to enter the steamspace, andalso in a means of filling the oilcup, which is effected bysuetion.

Referring to the accompanying drawings,

Figure 1 is an elevation of an apparatus ernbedying my invent-ion, shown partly in section. Fig. 2 isa section of the same on line a represents an oil-cup of any suitable dimensions. tena'od Z). and below the piston, respectively.

the top of the oiLcup, and is held and guided by a frame, 0. On the piston b, above the top of the oil-cup, is a collar, b forming a shoulder supporting a coiled spring, (I, surrounding the pistonrod and bearing against the un der side of the top of the frame a, as shown. (1 is a handle by which the pistonrod is raised.

' At one side of the oil-cup is apassage, e, err-- tending from. the upper end of the oil-cup a to a pipe, f, communicating with the main steam- The pipef, it will be seen, is below the level of the interior lower end of the oil-cup a. The passage 6 extends below the pipe f and connects with a glass-sight feed-tube, h. At the lower end of the feed-tube h is a hollow nipple, if, to

At one side of the lower end of the oil-cup o is con-nected a pipe, I, provided with a valve, oar-and through which the oil-cup is filled from any convenient receptab is a piston attached to the pis-- soend by its own gravity.

olesuch as a basin-held to the lower end of pipe Z.

The operation is as follows: ing at the bottom of the oil-cup and the valve 022 being open, a basin containing oil is applied or held to the lowcrend of pipe, which is immersed in the oil. The piston is then drawn up'by means of the handle 11, causing the oil to pass up through pipe Z and filling the oilcup. The valve mis then closed. The valve 9 in pipe f is then opened, thus admitting steam from the main steam-pipe to the passage e, and thence into the upper part, a, of the oil-cup, above piston I). At the same time steam passes downward from pipe f into the sight feed-tube h, and thence through nipple i to the passages j j, and up to valve k, which is closed. The feed-tube h and passages jj" soon become filled with water of condensation. Valve is is now opened, when the pressure of steam is equalized above and below the oil in oil-cup a, leaving theoil free to act, as if with out pressure. The pipe f, being on a lower level than the oil in the cup 0, and the water of condensation in passagesj 9" being heavier than the'oil above it, the oil forces downward the water in passagej, and passes up through the water in passage j the nipple '1', and the sight feed-glass it into pipe f, and thence into pipef. The amount of opening of valve it determines the quantity of oil which will flow and regulates the same. As the oil leaves the oil-cup the piston I), on its surface, also descends, any friction of the piston being overcome by the pressure of the spring (I.

The latter, however, is not absolutely necessary for carrying out the operation.

The piston-rod b may be detachably connected to the piston b, and removed from the same, when the latter will be left free to de- The piston-rod may also be made hollow and connect with an opening in the piston, so as to admit of oil being fed to the cup through the piston-rod.
